Dreadful game - poor graphics (at least in events - they obviously spent some time on locations).
Commentary dreadful - boring, very repetitive and and in any way related to what your performance is like (eg. I had three personal bests in high jump, was in the lead and then told I was bitterly disappointed and hadn't reached my potential).
Very few of the events represented and the obvious one (such as boxing) omitted, not only that but very few women's events - except the obviously sexist beach volleyball (where the men are missing).
All in all a poorly thought out series of 'bash a single key as fast as you can' events that quickly become incredibly tediious.
If you want Olympic excitement sticking your head in a buck of water would be a better approximation tot he water sports.
Seriously disappointing and a complete waste of time and money.
And to add insult to injury you NEED a game pad - this is a port from consoles where absolutely no effort has been made to get useful keyboard and mouse combinations for PC users. Basically if you look at the lettering (not the layout) on an XBOX360 pad they have translated the keyboard keys directly by letter - not by useful position and so so events are almost unplayable with keyboard and mouse.
